In this correspondence, we investigate the performance of a multi-cell multiple-input multiple-output downlink (DL) system aided by base station (BS) cooperation, relay cooperation, and polarization-multiplexing (PM).Triply-polarized antennas that Miele are employed at the BSs, relays, and mobile stations (MSs) to conceive PM serve as an replacemen
We have investigated waiting times for maxi-dresses taxis at the airport taxi stand at Oslo Airport Gardermoen, under two different regulatory systems, one allowing taxis to wait at a taxi stand directly in front of the airport and at a near depot and one only allowing for waiting at the depot.We Cloth Dust Bag find that waiting times for taxis dro
Abstract Background The incidence of dengue, an infectious disease caused by dengue virus (DENV), has dramatically increased around the world in recent decades and is becoming a severe public health threat.However, there is currently no specific treatment for dengue fever, and licensed vaccine against dengue is not available.Vaccination with virus-
Wireless sensor Networks (WSNs) deployed in distributed Internet of Things (IoT) applications should be integrated Box Bag into the Internet.According to the distributed architecture, sensor nodes measure data, process, exchange information, and perform collaboratively with other sensor nodes and end-users, which can be internal or external to the
This paper proposes a dual risk model with liquid reserve and proportional investments, this model is more suitable for real life.We derive the integral differential equations for the expected total discounted dividends before ruin.Since the exact solution of the equations does not exist, we obtain the approximate solution expression and further de
